Don't ignore the harm of early gastric cancer

The early symptoms of gastric cancer are related to the location and size of the tumor, as well as the duration of the disease. However, most of the early symptoms of gastric cancer are not very obvious, and only careful observation can reveal abnormalities.

1. Loss of appetite: Loss of appetite, accompanied by weight loss, gradual emaciation, or bloating and belching after eating, aversion to meat, etc. are common symptoms of gastric cancer.

2. Bleeding can occur in early gastric cancer, often manifested as tarry stools. In late gastric cancer, the amount of bleeding is large. If there is pyloric obstruction, coffee-colored or dark red blood is often mixed in the vomitus. The stool occult blood test is positive.

3. Nausea and vomiting are early symptoms of gastric cancer: Since most gastric cancers are located in the pyloric antrum, pyloric obstruction is quite common. Atypical early obstruction can cause a feeling of bloating after eating, mild nausea, and regurgitation, while typical mechanical pyloric obstruction causes gastric distension and vomiting. Vomitus is mostly food that has stayed in the stomach for too long, so it has a sour and rancid smell. Diffuse gastric cancer often does not have symptoms of obstruction and vomiting.

4. Stomach pain is a common early symptom of gastric cancer: the pain is mainly in the pit of the stomach, and sometimes it is only upper abdominal discomfort or dull pain. The more typical pain is irregular and is not relieved by eating.

5. Other early symptoms of gastric cancer: diarrhea, constipation, low fever, edema, and general exhaustion. When the tumor ruptures or causes perforation of the stomach wall, complications such as heavy bleeding and peritonitis may occur.
